RegularEx pressionValidator的文本框里面的GridView不工作 [英] RegularExpressionValidator for textbox inside GridView not working

问题描述

我的GridView：

 ＆LT; ASP：GridView控件ID =MyGridView=服务器ShowFooter =真
                                的AutoGenerateColumns =FALSE可见=真＆GT;
＆LT;柱体和GT;
＆LT; ASP：BoundField的数据字段=IDItemStyle-Horizo​​ntalAlign =中心/＆GT;
＆LT; ASP：BoundField的数据字段=全名/＆GT;
＆LT; ASP：的TemplateField的HeaderText =局面＆GT;＆GT;
＆LT;＆ItemTemplate中GT;
  ＆LT; ASP：DropDownList的ID =dl_situation=服务器＆GT;
   ＆LT; / ASP：DropDownList的＆GT;
＆LT; / ItemTemplate中＆GT;
＆LT; / ASP：的TemplateField＆GT;＆LT; ASP：的TemplateField＆GT;
 ＆LT;＆ItemTemplate中GT;
         ＆LT; ASP：文本框ID =TBNR=服务器＆GT;＆LT; / ASP：文本框＆GT;
＆LT; / ItemTemplate中＆GT;
＆LT; / ASP：的TemplateField＆GT;
＆LT; ASP：的TemplateField的HeaderText =数据＆GT;
＆LT;＆ItemTemplate中GT;
 ＆LT; ASP：文本框ID =tbDate=服务器＆GT;＆LT; / ASP：文本框＆GT;
 ＆LT; / ASP：＆的RequiredFieldValidator GT;
 ＆LT; / ItemTemplate中＆GT;
＆LT; / ASP：的TemplateField＆GT;
＆LT; /专栏＆GT;
＆LT; / ASP：GridView的＆GT;
 

这工作得很好，当我添加RegularrEx pressionValidator为ID =tbDate文本框my​​grid不起作用
此正前pression必须接受格式日期时间DD.MM.YYYY

 ＆LT; ASP：GridView控件ID =MyGridView=服务器ShowFooter =真
                                的AutoGenerateColumns =FALSE可见=真＆GT;
＆LT;柱体和GT;
＆LT; ASP：BoundField的数据字段=IDItemStyle-Horizo​​ntalAlign =中心/＆GT;
＆LT; ASP：BoundField的数据字段=全名/＆GT;
＆LT; ASP：的TemplateField的HeaderText =局面＆GT;＆GT;
＆LT;＆ItemTemplate中GT;
  ＆LT; ASP：DropDownList的ID =dl_situation=服务器＆GT;
   ＆LT; / ASP：DropDownList的＆GT;
＆LT; / ItemTemplate中＆GT;
＆LT; / ASP：的TemplateField＆GT;＆LT; ASP：的TemplateField＆GT;
 ＆LT;＆ItemTemplate中GT;
         ＆LT; ASP：文本框ID =TBNR=服务器＆GT;＆LT; / ASP：文本框＆GT;
＆LT; / ItemTemplate中＆GT;
＆LT; / ASP：的TemplateField＆GT;
＆LT; ASP：的TemplateField的HeaderText =数据＆GT;
＆LT;＆ItemTemplate中GT;
 ＆LT; ASP：文本框ID =tbDate=服务器＆GT;＆LT; / ASP：文本框＆GT;
 ＆LT; ASP：RegularEx pressionValidator ID =RegularCert=服务器
      的ControlToValidate =tbDate的ErrorMessage =Incorect数据
 ValidationEx pression =
（0 [1-9] | [12] [0-9] | 3 [01]）[ - ]（0 [1-9] | 1 [012]）[ - ]（19 | 20） 0-9] {2}
      显示=动态＆GT;＆LT; / ASP：RegularEx pressionValidator＆GT;
     ＆LT; ASP：的RequiredFieldValidator ID =RequiredFieldValidator1=服务器
      的ErrorMessage =*的ControlToValidate =tbDate＆GT;
   ＆LT; / ASP：＆的RequiredFieldValidator GT;
 ＆LT; / ItemTemplate中＆GT;
＆LT; / ASP：的TemplateField＆GT;
＆LT; /专栏＆GT;
＆LT; / ASP：GridView的＆GT;
 

解决方案

我改变了的ClientIDMode 到 predictable 为文本框， RegularEx pressionValidator 和的RequiredFieldValidator 并开始工作。

I have GridView:

<asp:GridView ID="MyGridView" runat="server" ShowFooter="true"
                                AutoGenerateColumns="False" Visible="True">
<Columns>
<asp:BoundField DataField="id" ItemStyle-HorizontalAlign="center"/>
<asp:BoundField DataField="fullName"  />
<asp:TemplateField HeaderText="situation>">
<ItemTemplate>
  <asp:DropDownList ID="dl_situation" runat="server">
   </asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>

<asp:TemplateField>
 <ItemTemplate>
         <asp:TextBox ID="tbNr" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>  
<asp:TemplateField HeaderText="Data">
<ItemTemplate>
 <asp:TextBox ID="tbDate" runat="server"></asp:TextBox>
 </asp:RequiredFieldValidator>
 </ItemTemplate>
</asp:TemplateField>     
</Columns>
</asp:GridView>

It work fine, but when I add RegularrExpressionValidator for textbox with id="tbDate" mygrid does not work This regular expression must accept datetime in format "dd.MM.yyyy"

 <asp:GridView ID="MyGridView" runat="server" ShowFooter="true"
                                AutoGenerateColumns="False" Visible="True">
<Columns>
<asp:BoundField DataField="id" ItemStyle-HorizontalAlign="center"/>
<asp:BoundField DataField="fullName"  />
<asp:TemplateField HeaderText="situation>">
<ItemTemplate>
  <asp:DropDownList ID="dl_situation" runat="server">
   </asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>

<asp:TemplateField>
 <ItemTemplate>
         <asp:TextBox ID="tbNr" runat="server"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>  
<asp:TemplateField HeaderText="Data">
<ItemTemplate>
 <asp:TextBox ID="tbDate" runat="server"></asp:TextBox>
 <asp:RegularExpressionValidator ID="RegularCert" runat="server" 
      ControlToValidate="tbDate" ErrorMessage="Incorect Data" 
 ValidationExpression=
"(0[1-9]|[12][0-9]|3[01])[-.](0[1-9]|1[012])[-.](19|20)[0-9]{2}" 
      Display="Dynamic"></asp:RegularExpressionValidator>
     <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
      ErrorMessage="*" ControlToValidate="tbDate">
   </asp:RequiredFieldValidator>
 </ItemTemplate>
</asp:TemplateField>     
</Columns>
</asp:GridView>

解决方案

I changed ClientIDMode to Predictable for TextBox, RegularExpressionValidator and RequiredFieldValidator and began to work
